Material Notes:
- m$ P: ]) u( r- w/ x% U$ N lSS4004P, SS4044P, SS4120, SS4155, and SS4179 primers are formulated for use with GE Silicones RTV silicone rubber adhesive sealants.? GE Silicones one-component products offer primerless adhesion to many substrates.? Primers are used to help promote adhesion to difficult-to-bond substrates.? For most GE Silicones two-component products, a primer is required when an adhesive bond is needed between the silicone rubber compound and a non-silicone surface (see table below).? All primers are one-component products requiring no mixing and are supplied ready-to-use as easily pourable solvent solutions., n9 l! K" A9 @- }0 M f8 Z
